Top up the brake fluid if low, only use VW 501.14
Then make sure to keep the reservoir cap ON
Handbrake released
Chock car properly and use axle stand
Wear safety specs and gloves to be safe
Have your new caliper and line ready, as soon as you remove the old replace with the new and tighten to minimize spillage
I used an upturned bucket to keep the new caliper on whilst removing the old one
Make sure everything is tightened properly, wipe around and check for leaks.
Pump the brakes a few times before you drive it.
You may get away with not having to bleed but you may have...
